Assume that the elevator car is now being operated in the downward direction and the rope 5 is moving in the direction of arrow A. When the speed of the elevator car reaches a predetermined speed that exceeds the rated speed, the safety circuit of the speed governor (not shown) is activated.
is activated to open the elevator control circuit, brake the hoisting machine, and stop the elevator car. However, if the elevator car speeds up further for some reason, the sheave 3 rotates further, and the flyweight 6 rotatably supported by the sheave 3 also rotates around the shaft 3b in the same way as the sheave 3. The flyweight 6 rotates clockwise about the shaft 6a as shown by the dashed line in FIG. 1 due to centrifugal force.
When the speed of the elevator car reaches a predetermined value, the flyweight 6 kicks the pawl 7a of the ratchet 7 having a gear cutting structure, so the ratchet 7 rotates clockwise and the arm 8 fixed to the ratchet 7 rotates clockwise.
Rotate clockwise. As a result, the support portion 8a of the arm 8 holding the brake body 10 is
As a result, the brake body 10 begins to rotate clockwise around the shaft 17 due to its own weight. Next, the rod 14 of the brake body 10 is at a certain angle θ 1 with respect to the horizontal plane.
Then, as shown in FIG. 3, the gripper 11 comes into contact with the rope 5 and is pressed further downward by its frictional force, and the rope 5 is caught between the jaws 2. At this time, since the rod 14 slides inside the pivot 15 toward the left in the drawing, the spring 13 is compressed, and the lower edge of the spring seat 16 is moved toward the base 1.
The rod 14 is supported by and stops in a horizontal position,
The pressing force due to the deflection of the spring 13 brakes the movement of the rope 5 in the direction of arrow A. This braking then generates a relative movement between the descending car and the braked rope 5, which activates an emergency stop device provided on the car, so that the car stops.

１１を逆にはね返えす現象を起し、はさみ込み作
用がうまくゆかない。 In such a conventional device, the gripping action of the rope 5 between the gripper 11 and the jaws 2 is performed only by the frictional force between the gripper 11 and the rope 5. If the initial frictional force is not sufficient, this pinching action cannot be achieved reliably. This becomes a problem as the angle θ 1 of the rod 14 with respect to the horizontal line when the gripper 11 contacts the rope 5 becomes larger. That is,
This pinching action is caused by the spring 1 as shown in Figure 3.
This is only possible when a frictional force F 3 sufficient to overcome the push-up force F 1 due to the return force F of 3 is generated, so if the angle θ 1 is large, the push-up force F 1 with the same return force F increases and at the same time the push force F 2 becomes smaller, the frictional force F 2 becomes smaller, and the pinching action becomes difficult. Furthermore, when the elevator is running at high speed, the rope 5 vibrates while the elevator is running, so the gripper 1
1 comes into contact with the rope 5, the rope 4 causes a phenomenon in which the gripper 11 is bounced back, and the clamping action does not go well.
この発明は上記の点に鑑みなされたもので、常

Components with the same reference numerals as those in FIGS. 2 and 3 indicate the same components, and components having different structures but functioning in the same manner as the conventional ones are indicated by adding "'" to the same reference numerals. below,
The apparatus of the present invention will be explained using the drawings. 3′
is a sheave according to the present invention, and has a friction clutch 3 on the back side.
1 is provided. The sheave 3' and the shaft 3'b of the sheave 3' are attached in the same way as before, but the shaft 3'b
An inclined ratchet wheel 32 is fixed to the side end of the support base 4 . 33, a key 33a is fitted into a groove provided in the shaft 3'b extending from the rolling bearing 3'a to the central portion, and the key 33a is fitted into the groove provided in the shaft 3'b, and the key 33a is slidably moved in the length direction of the shaft 3'b.
Since a spring 34 is provided between the cannula 33 and the rolling bearing 3'a, the cannula 33 is normally separated from the rolling bearing 3'a by a gap d. Supported. 7' is rotatably attached to the cannula 33 so as to cover the outer periphery of the cannula 33, and is usually separated from the sheave 3' by a gap d by the projection 33b of the cannula 33, similar to the cannula 33'. The ratchet 7' supported by the ratchet 7' has a geared outer peripheral surface as in the conventional case, and a claw 33c that engages with the inclined ratchet wheel 32 is provided at the side end of the support base 4.
have. 8' is an arm integrally connected to the ratchet 7' by welding or the like, and has a support part 8'a at its tip that engages with the pin 12a of the head.

When the speed of the elevator car reaches a predetermined value and the speed of the elevator car reaches a predetermined value and the flyweight 6' kicks the claw 7'a of the ratchet 7' having a gear cutting structure, the ratchet 7' momentarily moves as shown in FIG. The arm 8' and the lever 35 fixed to the ratchet 7' also rotate clockwise as shown by the dashed line. At this time, the ratchet 7' tries to rotate clockwise along the pawl of the inclined ratchet wheel 32, so the ratchet 7' along with the slidably provided sleeve 33 resists the spring pressure of the spring 34 as shown by the dashed line in FIG. It is pushed towards the sheave 3' as shown.

む。 Next, when the ratchet 7' further rotates due to the inertia caused by the impact of the flyweight 6' mentioned above, it is pushed toward the sheave 3' by the height l of the claws of the inclined ratchet wheel 32 as shown in FIG. is friction clutch 3
1 to the sheave 3'. At this time, since the sheave 3' is rotating at a high speed, the ratchet 7' receives a strong rotational force through the friction clutch 31 and further rotates clockwise. At this time, as shown in FIG. 6, the braking body 10, which is rotating around the shaft 17 until the gripper 11 touches the rope 5, is connected to the sheave 3' via a lever 35 provided on the ratchet 7'. Because a strong pressing force F 4 is applied,
By overcoming the upward force F 1 due to the return force F of the spring 13, the gripper 11 securely clamps the rope 5.

る。 By the way, when the ratchet 7' rotates clockwise by the pitch of the pawl of the inclined ratchet wheel 32, the spring pressure of the spring 33 pushes the mantle 34 back towards the inclined ratchet wheel 32, so that the ratchet 7' also rotates by the pitch of the pawl of the inclined ratchet wheel 32. 32 and returns to the original position, but at that time the gripper 11 of the brake body 10 has sufficiently gripped the rope 5, so even if the pushing force F4 disappears, the frictional force F3 alone is sufficient to grip the rope. will be done.

If the angle θ 1 of the rod 14 with respect to the horizontal line when the gripper 11 contacts the rope 5 is large, that is, if the frictional force F 3 sufficient to overcome the return force F 1 of the spring 13 cannot be obtained, the lever 35 The push-down force F4 not only ensures that the rope 5 is caught, but also suppresses the rebound phenomenon of the gripper 11 due to the vibration of the rope 5.

くのでなく必要なときにしか働かないため、ミス
トリツプの恐れも生じない。 As described above, the present invention transmits the rotational force of the sheave to the ratchet using a power transmission device such as a friction clutch. Since the braking body is pushed down by a lever, it absorbs the repulsion caused by the tension of the rope when the gripper contacts the rope, and also reduces friction due to the instability of the coefficient of friction determined by the surface conditions of the gripper and the rope. The effects of force fluctuations can also be suppressed as much as possible. Further, since the force that strongly pushes down the brake body does not work all the time, but works only when necessary, there is no fear of mistrips.
尚、以上の説明では、くわえ金がロープに接触

ーにより制動体を押下げる場合について述べた
が、本発明はレバーによりただ単に制動体に弾み
をつけるように構成するだけでも従来の問題点を
ほぼ解消できる。 In the above explanation, when the gripper contacts the rope, the rotation of the sheave is transmitted to the ratchet and the brake body is pushed down by the lever. However, in the present invention, the lever simply applies momentum to the brake body. Most of the problems of the conventional method can be solved simply by configuring it so that it can be attached.
